Physicists in the US have created ultracold polyatomic molecules by trapping and cooling them directly in three dimensions. Led by John Doyle at Harvard University, the team used a standard device ...

In the chemistry of interstellar clouds, the three-atomic hydrogen ion plays a key role. In these reactions, also simple organic molecules form. Although H3+ is the simplest polyatomic molecular ...

To get Polyatomic Ion Particles in The First Descendant, you can kill any mission monster on Fortress. Mission monsters are the powerful yellow bar enemies that can spawn in during missions.

Polyatomic Ion Particles can only be found in the Fortress Region. To get them, you need to participate in missions and kill enemies with yellow health bars (aka boss monsters).

A polyatomic ion that was thus far inaccessible with conventional mass spectroscopy has now been uncovered using extremely short laser pulses. Catching a glimpse of this ion would open up new ...
